Is your feature request related to a problem? Please describe.

vitepress/src/client/app/composables/copyCode.ts

Lines 20 to 24 in 4b0b1ef

	let { innerText: text = '' } = sibling
	if (isShell) {
	text = text.replace(/^ *(\$|>) /gm, '')
	}

Use innerText will include element properties. Like block element will make text with trailing newline \n

Describe the solution you'd like

code copy remove trailing newline

And I'm not sure if all lang code copy should remove this hidden problem.

But should be removed in the shell lang . Because in SHELL env (like bash) or some termianl apps, there is a trailing newline in our copy, the command will to be executed directly after paste, which is dangerous.

Describe alternatives you've considered

If maintainer agree, I will submit a PR

if (isShell)
  text = text.replace(/^ *($|>) /gm, '').replace(/[\n\r]$/, '')

Yeah I agree it's dangerous. Better directly put .trim() there. Feel free to create a PR! 🙌
